I own a Dell 3169 - the one with the Core M 6Y30 processor. I like this machine so I want to keep using it but I want to upgrade the WiFi to something that supports 5 GHz. I jumped the gun and ordered an Intel 9260 M.2 card but now I'm unsure if it's going to work (mainly BIOS compatibility.) Anyone know? If not are there any WiFi cards that will work and support 5 GHz? Thanks.
